Title: Texturing for high density pixelated-led chips
Inventor: ANDREWS PETER SCOTT
IPC: H01L33/20
Filed: 2020-10-29
Abstract: A pixelated-LED chip includes an active layer with active layer portions, segregated by streets, that are configured to illuminate different light-transmissive substrate portions to form pixels. A light extraction surface of each substrate portion includes protruding features and light extraction surface recesses that may be formed by sawing. Underfill material may be provided between a pixelated-LED chip and a mounting surface, as well as between pixels and between anodes and cathodes thereof. Certain implementations provide light extraction surface recesses that are non-parallel to each street defined through the active layer. Certain implementations provide light extraction surface recesses that are non-aligned with (e.g., non-parallel to) anode-cathode boundaries of each anode-cathode pair. Such arrangements reduce a likelihood of cracking in portions of a pixelated-LED chip. Methods for fabricating pixelated-LED chips are also provided.

Title: Antimicrobial and antiviral, biologically active polymer composites effective against sars-cov-2 and other viral, bacterial and fungal targets, and related methods, materials, coatings and devices
Inventor: VACHON DAVID JOHN
IPC: A01N41/04
Filed: 2020-11-11
Abstract: Biologically active ion-exchange polymer salts are made by exchanging biologically active ionic agents onto organic ion exchange polymers. The activated polymers are uniquely surface active for use in a wide range of antibacterial, antifungal and antiviral coatings, materials, and devices, to minimize or prevent pathogen transmission and/or infection of a susceptible individual such as a patient in a hospital. The resultant coatings, materials, and devices are the foundation of a system enabling the construction of spheres of protection, for example to protect against transmission of COVlD-19 (SARS-CoV-2) coronaviruses and other viral and fungal pathogens in a clinical or institutional environment, for example hospitals, community institutions, cruise ships, and long-term care facilities. The activated ion-exchange polymer salts are process stable, allowing size reduction and formulation of the resulting powders into bulk polymers or polymer precursors to produce stable, biologically active polymer composites, including antimicrobial and antiviral polymer composites.

Inventor: MAY JASON
IPC: A61B17/70
Filed: 2021-03-04
Abstract: A spinal-surgery system having a rod receiver and/or a cap. The cap has a cylindrical body, opposing splay-resisting flanges, and an opposing rotation-preventing/rotation-resisting wings, each wing having a lateral rotation-preventing surface and a lateral rotation-resisting surface. A receiver proximal end forms a wing-receiving cavity having a lateral rotation-preventing side and a lateral rotation-resisting side. Each flange has a proximal-facing cap splay-resist surface, and a distal-facing cap pop-on surface. Each receiver proximal protrusion has a proximal-facing sloped receiver pop-on surface, and a distal-facing sloped receiver splay-resist surface. Each rotation-preventing surface contacts a corresponding rotation-preventing side and each rotation-resisting surface contacts a corresponding rotation-resisting sides when the cap is popped on. The rotation-preventing surfaces contacting the rotation-preventing sides prevents cap rotation in a first direction. The rotation-resisting surfaces contacting the rotation-resisting sides resists cap rotation in a second direction, but allows cap rotation in the second direction to force receiver arm splay.
